Protect your Wristop Computer from shocks, extreme heat and prolonged exposure to direct sunlight. If not in use, your Wristop Computer should be stored in a clean, dry environment at room temperature. The Wristop Computer can be wiped clean with a lightly moistened (warm water) cloth. Applying a mild soap to the area can clean stubborn stains or marks. Avoid exposing the Wristop Computer to strong chemicals like gasoline, cleaning solvents, acetone, alcohol, adhesives, and paint, as they will damage the units seals, case and finish. Never attempt to take the Wristop Computer apart or service it yourself. Make sure the area around the sensors (backside of the instrument) is kept free of dirt and sand. Never insert any objects into the sensor openings of the Wristop Computer.

1.7.1 Battery Replacement
The Wristop Computer operates on a three-volt lithium cell Type: CR 2430. The maximum life expectancy is approximately 12-18 months. A low battery-warning indicator is activated when 5-15 percent of the battery capacity is still available. When this occurs we recommend replacement of the battery. Extreme cold weather will activate the low battery-warning indicator. Though the indicator is activated, the battery may not need to be replaced due to this condition. In temperatures above 10C (50F) and the low battery warning indicator is activated, the battery will need to be replaced. Note: Heavy use of the electroluminescent backlight, altimeter, and compass will significantly reduce the life of the battery. To replace the battery: 1. turn the Wristop Computer to view the backside; 2. insert a coin in the coin slot located on the battery compartment cover; 3. turn the coin counterclockwise to the open position marked on the back of the case; 4. remove the battery compartment cover; 5. remove the old cell from the battery compartment and ensure the o-ring and all surfaces are clean, dry and not damaged. Do not stretch the o-ring; 6. place the new cell into the battery compartment (negative side down, positive side up); 7. ensure that the o-ring is in its place to keep the Wristop Computer waterproof. Place the battery compartment cover back onto the backside of the Wristop Computer; 8. insert a coin back into the coin slot; and 9. turn the coin clockwise to the close position marked on the back of the case. Note: Battery replacement should be performed with extreme care so as to ensure the Wristop Computer continues to remain waterproof.It is the operators responsibility to take due care to ensure that the Wristop Computer remains waterproof.
After every battery replacement, it is necessary to calibrate the magnetic sensor. Details on performing this process are found in Calibrating the Compass section of this manual.

When this occurs, hold the Wristop Computer level and start to slowly turn the device around a full circle in a level position. The
direction of turning does not matter. The lit segments will be turned off as the turning proceeds. When the first full circle is completed, the instrument will inform the user within one minute of whether the calibration was successful displaying the text dOnE in Field 2 (Fig. 37) or if the process needs to be repeated displaying PUSH and - in Field 2. Note: The user may need to perform the rotating of the compass more than twice around for the calibration to be completed. Note: During calibration, it is not necessary that all peripheral segments light up or turn off. Note: If the text FAIL appears in Field 2 (Fig. 38), the battery should be removed and put back in before trying to proceed with the calibration process. The removal of the battery will reset the unit. 5. Once the calibration is successful, PRESS the [Mode] button to accept the process and exit the calibration mode. Note: It is important to hold the Wristop Computer level during the calibration process to ensure accuracy. The compass calibration is complete.

6.3.5 What is the maximum capacity of total vertical ascent or descent feet/meters in the logbook history?
The maximum figure that can be shown on the display is 29,999.999 representing feet or meters depending on the unit of measurement set. This should be enough for most users: 29,999.999 meters is roughly threequarters around the globe.
6.3.6 If hiking from a level of 5,000 ft down hill to 3,000 ft and then back up to 8,000 feet, how is the Vector going to read this or average it out?
There are several answers to this question related to different situations. First, if you mean will Wristop Computer show accurate altitude information when ascending back to 8,000 ft after having descended to 3,000 ft from 5,000 ft, the answer is yes if the barometric pressure hasnt been affected by weather changes. Since the altitude is shown based on the atmospheric pressure reading it will be affected by pressure changes. But if the conditions are the same, and the reference altitude is set, the unit will show quite accurate readings. Second, if what you mean is how the Wristop Computer calculates the information shown in the logbook, this is what it does: for the total ascent during the log (the logbook recording has been activated by the user when starting out) it calculates the ascent from 3,000 ft to 8,000 ft, i.e. total ascent has been 5,000ft. For the descent it calculates the descent from 5,000 ft to 3,000 ft, i.e. total descent 2,000 ft.
Third, if thinking about the difference measurement function and how this is affected by the example situation, the Wristop Computer will show you the absolute difference between 5,000 ft and 8,000 ft (beginning and end). The fact that youve been down to 3,000 ft in-between does not have an impact on the absolute vertical altitude difference between starting point and finish. Last, the automatic 24-hour memory will show this information in the following way: Say you are starting out at 5,000 ft at noon, and then it takes you 2 hours to descend to 3,000 ft, and another five hours to reach 8,000 ft. The scrollable displays in the 24-hour memory shows you the altitude 5,000 ft at 12:00 am, e.g.4,000 ft at 1 p.m., 3,000 ft at 2 p.m., e.g. 4,000 ft 3 p.m., 5,000 ft at 4 p.m., 6,000 ft at 5 p.m., 7,000 ft at 6 p.m. and then 8,000 ft at 7 p.m. These are the different cases in which the example situation will affect the readings of the Wristop Computer. Most important to remember is to ALWAYS set the known reference altitude into the Wristop Computer. This is the only way to get accurate altitude readings.
6.3.7 Why does the vertical ascent/descent measurement show different readings even though I am inside and staying in the same room?
The resolution of the vertical ascent/descent rate is 1 m/1 ft whereas the resolution of the altitude display is 5 m/ 10 ft, which means that the ascent/descent rate can show movement even though you remain at the same altitude. This is caused by changes in pressure or even vertical movement within the 5 m/10 ft resolution range. Indoors, even small, unnoticeable air currents cause changes in air pressure. For example, if you have a window open at the other end of your house, the air current may affect a room at the other end of the building so little that you do not notice it, but the sensors of the Wristop Computer do. Because the Wristop Computer measures ascent and descent based on changes in air pressure, it interprets these changes as vertical movement.

1.7 CARE AND MAINTENANCE

Perform only the detailed processes discussed in this manual. Do not perform any other service to the Wristop Computer or attempt to open the case or remove the buttons or the bezel. Protect your Wristop Computer from shocks, extreme heat and prolonged exposure to direct sunlight. If not in use, your Wristop Computer should be stored in a clean, dry environment at room temperature. The Wristop Computer can be wiped clean with a lightly moistened (warm water) cloth. Applying a mild soap to the area can clean stubborn stains or marks. Avoid exposing the Wristop Computer to strong chemicals like gasoline, cleaning solvents, acetone, alcohol, adhesives, and paint, as they will damage the units seals, case and finish. Never attempt to take the Wristop Computer apart or service it yourself. Make sure the area around the sensors (backside of the instrument) is kept free of dirt and sand. Never insert any objects into the sensor openings of the Wristop Computer.
1.7.1 Battery Replacement

The Wristop Computer operates on a three-volt lithium cell Type: CR 2430. The maximum life expectancy is approximately 12-18 months. A low battery-warning indicator is activated when 5-15 percent of the battery capacity is still available. When this occurs we recommend replacement of the battery. Extreme cold weather will activate the low battery-warning indicator. Though the indicator is activated, the battery may not need to be replaced due to this condition. In temperatures above 10C (50F) and the low battery warning indicator is activated, the battery will need to be replaced. Note: Heavy use of the electroluminescent backlight, altimeter, and compass will significantly reduce the life of the battery. To replace the battery: turn the Wristop Computer to view the backside; insert a coin in the coin slot located on the battery compartment cover; turn the coin counterclockwise to the open position marked on the back of the case; remove the battery compartment cover; remove the old cell from the battery compartment and ensure the o-ring and all surfaces are clean, dry and not damaged. Do not stretch the o-ring; 6. place the new cell into the battery compartment (negative side down, positive side up); 7. ensure that the o-ring is in its place to keep the Wristop Computer waterproof. Place the battery compartment cover back onto the backside of the Wristop Computer; 8. insert a coin back into the coin slot; and 9. turn the coin clockwise to the close position marked on the back of the case. Note: Battery replacement should be performed with extreme care so as to ensure the Wristop Computer continues to remain waterproof.It is the operators responsibility to take due care to ensure that the Wristop Computer remains waterproof. After every battery replacement, it is necessary to calibrate the magnetic sensor. Details on performing this process are found in Calibrating the Compass section of this manual. 1. 2. 3. 4. 5.

CHAPTER 2

TIME MODE
The Time Mode provides the user with: an adjustable 24/12 hour clock display; a calendar pre-programmed to the year 2089; and three sub modes: three daily alarms, stopwatch and countdown timer.
To view and use the Time mode: Check the Mode Indicator Bar. If the mode arrow is not on TIME, PRESS the [Mode] button until the arrow is directly below TIME on the bar. In the TIME mode (Fig. 10): Field 1 displays the day of the week. Field 2 displays the current time. Field 3 displays the date (month/day). The Outer Circumference graphically displays time in seconds.

Note: In selecting the interval, the user chooses a) the time period for recording the altitude, the vertical ascent/ descent rate as well as the current time to be stored into the logbook and b) the timeout or maximum recording time of a logbook. The shorter the interval the more accurate the information due to the fact the sampling rate is faster. Timeouts are discussed on page 25. 9. At the desired interval, PRESS the [Mode] button to accept the changes and exit the setup program. Once the user completes the process in setting the reference altitude of the current location to the known altitude, the Wristop Computer will also correct the sea level pressure, and therefore, it will not be necessary for this function to be set. Note: If the user does not press any button for 1 minute in the setup mode, the display will automatically exit setup. Note: A 10-minute recording interval means that the Wristop Computer records data every 10 minutes.
3.2 ALTITUDE DIFFERENCE MEASUREMENT SUB MODE

This feature is always displayed in all main modes providing the user a continual quick reference to analyze upcoming weather conditions. The Barometric trend is comprised of two lines forming an arrow. Each line represents a 3-hour period. The right line represents the last 3 hours. The left line represents 3 hours prior to the last 3 hours. The line can indicate 9 different patterns in the barometric trend. Situation 6-3 hours ago Dropped heavy (>2 mbars/3hours) Dropped heavy (>2 mbars/3hours) Dropped heavy (>2 mbars/3hours) Remained stable Remained stable Remained stable Risen heavy (>2 mbars/3hours) Risen heavy (>2 mbars/3hours) Risen heavy (>2 mbars/3hours) Situation last 3 hours Dropping heavy (>2 mbars/3hours) Remaining stable Rising heavy (>2 mbars/3hours) Dropping heavy (>2 mbars/3hours) Remaining stable Rising heavy (>2 mbars/3hours) Rising heavy (>2 mbars/3hours) Remaining stable Dropping heavy (>2 mbars/3hours)
Note: If the user remains at the same elevation, the barometric trend indicator can work as a weather forecasting tool.
CHAPTER 5 COMPASS MODE (VECTOR AND X-LANDER)
Note: This function applies to the Vector and X-Lander. The compass mode provides the user with: a cardinal or half cardinal point abbreviation;
bearing degrees; a North-South arrow; a bearing track mode showing desired direction and actual bearing; a bubble level for accuracy reading +3 degrees (only in the Vector); a rotating bezel; a resolution of 1 for the bearing, +5 for North-South direction; and a declination correction feature.
To view and use the Compass Mode: Check the Mode Indicator Bar. If the mode arrow is not on COMP, PRESS the [Mode] button until the arrow is directly below COMP on the bar. In the COMPASS mode (Fig. 6): Field 1 displays the cardinal or half-cardinal point. Field 2 displays the bearing in degrees. Field 3 displays the current time. The Outer Circumference graphically displays the North-South arrow where one-lit segment shows North and three-lit segments show South.
The Wristop Computer provides a bubble level for the user to achieve a precise reading within +3 degrees. The user should acquire a bearing by removing the Wristop Computer from the wrist. The user centers the liquid bubble to ensure the Wristop Computer position is level and takes a reading. The compass display is active for 45 seconds at a time. After this, the compass enters sleep mode and an -- indicator appears in the field 2. Reactivate the compass by pressing the [-] button. Note: Compass readings should be performed away from objects possessing sources of magnetism. Avoid buildings, large metal objects, power lines, loudspeakers, electric motors etc. Always take bearings in the open air, not inside tents, caves, or other shelters.

5.1 BEARING TRACKING SUB MODE
The user can select to change from the cardinal point mode to the bearing track function and utilize the bearing lock function in this mode for tracking purposes (Fig. 7). In the compass main mode: 1. PRESS the [Select] button and hold in for 2 seconds. Located in Field 1, OFF will begin to flash (Fig. 8). 2. PRESS either the [+] or the [-] button to change the setting between OFF and ON. 3. At the selection desired, PRESS the [Select] button to move to the next setting. Located in Field 2, the actual bearing in degrees will begin to flash (Fig. 9). 4. Turn the Wristop Computer to the desired direction. Lock the bearing displayed by pressing the [-] button. 5. Adjust the locked bearing, if necessary by pressing the [Select] button and then adjusting the value with the [+] and [-] buttons. 6. At the desired bearing to track, PRESS the [Mode] button to accept the changes and exit the setup program. Note: If the user does not press any button for 1 minute in the setup mode, the display will automatically exit setup. Note: Locking in the Bearing Tracking submode blocks the compass reading.
5.2 DECLINATION ADJUSTMENT SUB MODE
The Wristop Computer allows the user to compensate the difference between true north and magnetic north. This process is accomplished by adjusting the declination, resulting in the user obtaining correct compass readings. In the Compass mode, PRESS the [Select] button once to enter this sub mode. In the Declination Adjustment sub mode (Fig. 33): Field 1 displays the declination direction OFF where OFF = no declination; W = West; E = East. Field 2 displays declination in degrees. Field 3 displays the text dEC.
5.2.1 Setting the Local Declination
1. PRESS the [Select] button and hold in for 2 seconds. Located in Field 1, OFF will begin to flash. 2. PRESS either the [+] or the [-] button to change the declination direction in Field 1. 3. At the direction desired, PRESS the [Select] button to move to the next setting. Located in Field 2, the degrees will begin to flash. 4. PRESS the [+] button to scroll the degrees upward or PRESS the [-] button to scroll the degrees downward. 5. At the degrees desired, PRESS the [Mode] button to accept the changes and exit the setup program. Note: If the user does not press any button for 1 minute in the setup mode, the display will automatically exit setup. Local Declination is now set.

6.3.3 How many logbooks can you record?
The number of logs you can record into the logbook depends on the chosen interval and the length of each log. For example, if your interval is 1 minute, you can get a total of 3,800 minutes of logs into the logbook. This equals 2.64 days if the recording is continuous (24 hours = 1,440 minutes; 3,800/1,440=2.64).
To avoid excessive battery drain, the recording is not continuous. The recording functions have certain timeouts (i.e. the recording will be turned off automatically after a certain time). The timeouts are shorter for the faster interval and longer for the slower interval.
6.3.4 What is the duration readout?
The duration readout tells you how many hours and/or minutes the event recorded into the logbook lasted. For example, if youre hiking from 1 p.m. to 6 p.m. and the logbook is on during this time, the readout would show a duration of 05:00 hours.
6.3.5 What is the maximum capacity of total vertical ascent or descent feet/meters in the logbook history?
The maximum figure that can be shown on the display is 29,999.999 representing feet or meters depending on the unit of measurement set. This should be enough for most users: 29,999.999 meters is roughly threequarters around the globe.
6.3.6 If hiking from a level of 5,000 ft down hill to 3,000 ft and then back up to 8,000 feet, how is the Vector going to read this or average it out?
There are several answers to this question related to different situations. First, if you mean will Wristop Computer show accurate altitude information when ascending back to 8,000 ft after having descended to 3,000 ft from 5,000 ft, the answer is yes if the barometric pressure hasnt been affected by weather changes. Since the altitude is shown based on the atmospheric pressure reading it will be affected by pressure changes. But if the conditions are the same, and the reference altitude is set, the unit will show quite accurate readings. Second, if what you mean is how the Wristop Computer calculates the information shown in the logbook, this is what it does: for the total ascent during the log (the logbook recording has been activated by the user when starting out) it calculates the ascent from 3,000 ft to 8,000 ft, i.e. total ascent has been 5,000ft. For the descent it calculates the descent from 5,000 ft to 3,000 ft, i.e. total descent 2,000 ft.
Third, if thinking about the difference measurement function and how this is affected by the example situation, the Wristop Computer will show you the absolute difference between 5,000 ft and 8,000 ft (beginning and end). The fact that youve been down to 3,000 ft in-between does not have an impact on the absolute vertical altitude difference between starting point and finish. Last, the automatic 24-hour memory will show this information in the following way: Say you are starting out at 5,000 ft at noon, and then it takes you 2 hours to descend to 3,000 ft, and another five hours to reach 8,000 ft. The scrollable displays in the 24-hour memory shows you the altitude 5,000 ft at 12:00 am, e.g.4,000 ft at 1 p.m., 3,000 ft at 2 p.m., e.g. 4,000 ft 3 p.m., 5,000 ft at 4 p.m., 6,000 ft at 5 p.m., 7,000 ft at 6 p.m. and then 8,000 ft at 7 p.m. These are the different cases in which the example situation will affect the readings of the Wristop Computer. Most important to remember is to ALWAYS set the known reference altitude into the Wristop Computer. This is the only way to get accurate altitude readings.
